Biomphalaria molluscs (Gastropoda: Planorbidae) in Rio Grande do Sul, Brazil

Memorias do Instituto Oswaldo Cruz, 2009
The present study was aimed at characterising Biomphalaria species using both morphological and molecular (PCR-RFLP) approaches. The specimens were collected in 15 localities in 12 municipalities of the southern region of the state of Rio Grande do Sul ...

Gastropod-Borne Helminths: A Look at the Snail-Parasite Interplay. [PDF]

, 2015
More than 300 million people suffer from a range of diseases caused by gastropod-borne helminths, predominantly flatworms and roundworms, whose life cycles are characterized by a diversified ecology and epidemiology. Despite the plethora of data on these

Habitat Structure Shapes Mollusc Assemblages in an Urban Semiarid River: Implications for Conservation and Public Health

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Fine‐scale environmental drivers shape freshwater mollusc assemblages in urban semiarid rivers. We examined how substrate composition and water chemistry influence mollusc richness and abundance along a polluted stretch of a river in the Brazilian semiarid region. Surveys at five sites recorded 2479 individuals.

Identification of Biomphalaria sp. and other freshwater snails in the large-scale water transposition project in the Northeast of Brazil

Revista do Instituto de Medicina Tropical de São Paulo, 2018
The wide eco-bio-social intervention generated by the SaoFrancisco River Integration Project (PISF) may contribute to the dispersion or introduction of schistosomiasis intermediate hosts in areas without prior recording. The objective was to characterize

Differentiation of Schistosoma haematobium from related schistosomes by PCR amplifying an inter-repeat sequence. [PDF]

, 2007
Schistosoma haematobium infects nearly 150 million people, primarily in Africa, and is transmitted by select species of local bulinid snails. These snails can host other related trematode species as well, so that effective detection and monitoring of ...

Taxonomic Deception via Obvious Traits: Oversplitting in European Vallonia Risso, 1826 (Mollusca: Gastropoda: Valloniidae)

Zoologica Scripta, Volume 55, Issue 1, Page 37-51, January 2026.
ABSTRACT The status of the six traditionally recognised European Vallonia taxa is considered based on mtDNA and nDNA sequences from five independently sorting loci in combination with morphometric landmark analyses conducted on genetically confirmed shells. These analyses document that only two species are valid (V. costata and V.

The Pampulha reservoir remains a potential urban focus of schistosomiasis mansoni in Brazil: changes in the occurrence patterns of Biomphalaria species and a new record of the parasite

Revista da Sociedade Brasileira de Medicina Tropical, 2013
Introduction The Pampulha reservoir has long been a focus of schistosomiasis transmission in Belo Horizonte, State of Minas Gerais, Brazil. The last malacological study conducted in this urban reservoir was more than two decades ago, and thus, an update ...

Zoonotic Schistosomiasis: The Crossroads Between Animal and Human Schistosomiasis in Africa: Narrative Review

Health Science Reports, Volume 8, Issue 11, November 2025.
ABSTRACT Background The fight against schistosomiasis (urogenital and intestinal) has prolonged more than expected with more areas that were previously known to have less or no incidence of infection now recording alarming incidence rate. Researchers and stakeholders are now concerned about what is probably sustaining the possible infection, and one of

Seleção genética de Biomphalaria glabrata e Biomphalaria tenagophila visando a alteração da suscetibilidade e resistência ao Schistosoma mansoni Genetic selection of Biomphalaria glabrata and Biomphalaria tenagophila seeking the alteration of the susceptibility and resistance to the Schistosoma mansoni

Revista da Sociedade Brasileira de Medicina Tropical, 2005
Gerações de Biomphalaria glabrata e Biomphalaria tenagophila selecionadas geneticamente para resistência e suscetibilidade ao Schistosoma mansoni das linhagens BH e SJ foram utilizadas no estudo da adaptação do trematódeo ao hospedeiro intermediário.
